(Yeah, I'm new - be kind please.) I've already Googled, and looked through the MTurk site help (boy that isn't much, is it) and Forum here, but didn't see something that would guide me... Several times I've accepted HITs, gone to work on them in a separate tab, then when I went back to the original "accepting" tab to input my required survey -or whatever-code for completion and to hit Submit - I am dismayed to see only the regular listings, and a error message "This HIT has expired" What!! I used Accept Hit, I had no problems in working on the HIT itself...did I simply take too long? (that couldn't be, I know the "timer" could not have run out that quickly.) So, did I just work for nada? What does it mean? Any way around it?
